The system enables the car to drive semi-automatically up to a speed of 130km per hour on motorways and is intended to prevent accidents due to driving errors by drivers not focusing on road conditions.

The technology uses production-level radar-, camera- and ultrasonic-based sensors supplemented by a laser scanner and an electronic horizon.

In the semi-automatic driving mode – or "Pilot Mode" – TAP maintains a safe distance from the vehicle ahead, drives at a speed selected by the driver, reduces this speed as necessary before a bend and maintains the vehicle’s central position with respect to lane markers. The system also observes overtaking rules and speed limits. It can also be used to automate stop and start driving manoeuvres in traffic jams. However, the driver must always focus on the road conditions and can over-ride the system at any point.

The technology was presented at the EU research project HAVEit (Highly Automated Vehicles for Intelligent Transport).
